Variance and multiple regression analyses showed certain degree of relationship of disease incidence to coconut age level, relative dominance of some weed species, namely; Imperata cylindrica, Mikania cordata and Paspalum conjugatum, incidence of the rhinoceros beetle, Oryctes rhinoceros, soil acidity, exchangeable bases and textural grade of soil. The direct and indirect roles of the ecological factors in disease development, however, have to be established yet.
